So, you bought a house for $1m and a year later someone offers you $900k for it. Will you sell it? Why should you? If you're not in debt, have money to pay your bills, you won't sell it, right?
A person who bought house for $1m and sold for $900k within the interval of 1 Year must really be insane or could have involved in a financial challenges. But no matter what
, selling asset to quickly earlier than expected
is not Good because it will lead to selling at Lost. So if you ask me I will say i wouldn't sell it until I meet my set target or probably allow it to compound.
